  • There is still one another computer peripheral charge device that charge by way of reaction method, for example Taiwan issued patent No. 555286(applied on Dec. 7, 2001 and published on, Sep. 21, 2003) “The electric magnetic reaction charge device of a personal digital assistant” is related to a electric magnetic reaction charge device for a personal digital assistant (PDA), wherein, the electric magnetic reaction charge device of the PDA comprises: an electric magnetic reaction charge base, for converting a charging energy into a reaction current and passing to the PDA; and an electric magnetic reaction charge interface, for embedding the PDA into the electric magnetic reaction charge base and receiving the reaction current from the electric magnetic reaction charge base. The prior par patent uses electric magnetic reaction way to pass the electric energy. However, it also does not have ability to detect the load varying, the induction coil continually converting the power when the peripheral charge device need not to be charged, so that causes the power wasting due to power converting.
  • According to the aforesaid description, the contact type charge device has the following drawbacks: (1) the prior art charge devices used contact pad(s) have already been eliminated gradually due to their bad contacting drawback; (2) the charge devices do not have ESD (ESD/electro-static discharge) protecting ability due to the contact pad of the charge devices have been exposed in the air long time. Furthermore, the aforesaid reaction type charge devices, do not have ability to detect the load varying, the induction coil continually converting the power when the peripheral charge devices need not to be charged, so that causes the power wasting due to power converting. Therefore, there need a pulse frequency modulation for induction charge device which can generate pulse singles with various frequencies according to the load varying generated due to distance varying between the portable electronic device and the charged device, and charge to the portable electronic device according to the pulse singles so as to reach the goal of effective management the power and overcome the aforesaid drawbacks of the prior art.

  • Referring to FIGS. 5 and 6, which respectively illustrates a circuit diagram of the pulse frequency modulation for induction charge device 1 and the portable electronic device 2 according to one prefer embodiment of the present invention. As shown in the Figs., the working principle of the pulse frequency modulation for induction charge device 1 and the portable electronic device 2 of the present invention is shown as following: at first, the power Vcc is passed to the detection and modulation generate circuit 14 (consists of resistor R1, diode D5, capacitor C2, C3, modulation generating circuit U1) through the power input port 12, control switch circuit 15 (consists of transistor Q1, resistor R2, R6, diode D6, and LED 1), the electric magnetic field generate and the secondary coil react circuit (consists of the primary coil L11 and the secondary coil L12) as the reference voltage. When the voltage lower than the reference voltage, the modulation generating circuit U1 of the detection and modulation generate circuit 14 will continually output pulse signals. When the voltage higher than the reference voltage, the modulation generating circuit U1 of the detection and modulation generate circuit 14 will discontinuity output pulse signals with very low frequency.
  • When the power is initially inputted, the power voltage is dropped by the aforesaid elements, thus makes the reference voltage lower than the preset voltage (for example but not limited to DC 5V, and can be changed depending on requirement), the detection and modulation generate circuit 14 will output pulse signals to the control switch circuit 15 and actuate the transistor Q1. Further, the primary coil L11 of the electric magnetic field generate and the secondary coil react circuit 13 receives the voltage and generates electric magic field. The secondary coil L12 will react a voltage cascaded to the Vcc and supply to the detection and modulation generate circuit 14 when the electric magic field of the primary coil L11 is switched, meanwhile the detection and modulation generate circuit 14 can detect the voltage level. At this time, if the primary coil L11 approaches without additionally load (i.e. the induction coil 21, rectification circuit 22 (consists of the diode D1, D2, D3, D4 and capacitor C1), rechargeable battery 23, device circuit 24), the voltage reacted by the secondary coil L12 will increase, and when the voltage level is equal to the reference voltage, the detection and modulation generate circuit 14 will stop outputting the pulse signals, until the voltage is lower than the reference voltage by way of discharging, and the detection and modulation generate circuit 14 will discontinuity output pulse signals with very low frequency and detect the additionally load being appeared or not, so as to prevent power from wasting. Furthermore, the portable electronic device 2 of the present invention further comprises a switch circuit 25 positioned between the rechargeable battery 23 and the device circuit 24 for controlling the device circuit 24 working or not. Wherein, the switch circuit 25 is a manual switch SW1 or automatic switch. If the switch circuit 25 is an automatic switch, please refer to FIG. 6, the switch circuit 25 is consisted of a PMOSFET Q4, resistor R4, R5, transistor Q3 and diode D7.
  • At present, if the primary coil L11 approaches with additionally load (i.e. the portable electronic device 2), the voltage reacted by the secondary coil L12 will increase, and when the voltage level is equal to the reference voltage, the voltage reacted by the secondary coil L12 will slowly decrease due to the load effect. And the voltage reacted by the secondary coil L12 adding the Vcc voltage will even less the reference voltage when the additionally load even more approaches to the charge device (such as the portable electronic device 2 is positioned in the base seat 10 of the pulse frequency modulation for induction charge device 1, or the heights of the induction coil inside the different type portable electronic device 2 are different and use the same pulse frequency modulation for induction charge device 1). The voltage reacted by the secondary coil L12 adding the Vcc voltage will even less the reference voltage, and the detection and modulation generate circuit 14 will continuity output pulse signals with even higher frequency. The primary coil L11 generates electric magic field while the pulse signals passes it, and then the electric magic field is coupled to the induction coil 21 and rectified by the rectification circuit 22, finally, charges to the rechargeable battery 23. Therefore, the pulse frequency modulation for induction charge device 1 of the present invention can generate pulse singles with various frequencies according to the load varying generated due to distance varying between the portable electronic device 1 and the charged device, and charge to the portable electronic device 2 according to the pulse singles so as to reach the goal of effective management the power and overcome the aforesaid drawbacks of the prior art.
